A novel and selective palladium-catalyzed C-H activation protocol has been developed for the synthesis of 3-aryl quinolin-2(1H)-ones and 3-(1-arylmethylene)oxindoles with use of PivOH as the switch. In the presence of Pd(OAc)(2), AgOAc, and PivOH, a variety or N-methyl anilides reacted with arenes to afford the corresponding 3-aryl quinolin-2(l H)-ones in moderate yields, whereas the selectivity was shifted toward 3-(1-arylmethylene)oxindoles in the absence of PivOH.
Metal-Free Synthesis of 3-Arylquinolin-2-ones from Acrylic Amides via a Highly Regioselective 1,2-Aryl Migration: An Experimental and Computational Study
Combined experimental and theoretical investigations into the phenyliodine bis(trifluoroacetate) (PIFA)-mediatedreaction of N-arylcinnamamide to produce 3-arylquinolin-2-one derivatives have been conducted. High regioselectivity during the aryl migration process was observed in 3,3-disubstituted acrylamides. Density functional theory calculation was conducted in an attempt to understand the mechanism
